Aiming at the real-time problem of collection

calculation and communication of information of navigation sensing in conventional ammunition

present that combine direct memory access（ DMA） with traditional processing method of information to timely handle multi-channel sensing information of conventional missile.Analyze general requirement of processing technology of sensing information in navigation of conventional ammunition

and design hardware circuit according to the requirement. Introduce working principle of sensing information processing in traditional way and in DMA way. Design software and proves it by experiments. The result of this experiment indicates that the rate of information collection

calculation and communication of combination of DMA with traditional information processing method can be up to 3 times rate of traditional method

and it can satisfy the real-time request for information processing in navigation of conventional ammunition.
